Patented 9st. 4, 1932 OFFICE GUSTAV A. CABLSON, OF CHICAGO, T'LLINOIS,ASSIGNOR TO THE BOYE- NEEDLE COMPANY,

OF CHICAGO, ILLINOIS, A CORPORATION 01? ILLINOIS LOOP-FORMING NEEDLEApplication filed October 3, 1930 Serial No. 486,252.

This invention relates particularly to a needle adapted to the purposeof making rugs, or other articles, where it is desirable to pass yarnthrough a foundation fabric,

such as burlap, and form loops at one side of the fabric, thus providinga nap. The loops may afterwards be cut to permit the yarn to spread andform a fuzzy nap.

The present invention is in the nature of an 10 improvement upon thedevice disclosed in my pending application Serial No. 486,251, filed ofeven date herewith; and the primary object is to provide a simple andsecure form of connection between the needle, proper, of

a device of this character and its handle.

The invention is illustrated in a preferred embodiment in theaccompanying drawing, in which Fig. 1 is a side view of a needle deviceembodying the invention; Fig. 2, a plan view of the needle and thefitting or socket-member with which it is equipped; Fig. 8, a brokensectional view taken as indicated at line 3 of Fig. 2, showing in detailthe connection between the needle and handle; and Fig. 4, a transversesection taken as indicated at line 4: of Fig. 3.

In the illustration given, A designates a handle; and B, a semi-tubularneedle equipped with a fitting B which serves as a connector between theneedle and the handle.

The needlepreferably is of the construction described in theabove-mentioned ap- As shown, it is formed from a sheet-metal member 1which is bent into tubular form, but which has a portion cut away, asindicated at 2.

The needle has a pointed tip 3 and a tu- 40 bular shank-portion i. Theback wall of the needle is provided with eyes 5 and 6 through which theyarn may extend. As thus described, the needle has a longitudinalchanchine. As shown, it comprises a knurled portion 8 and a threadedshank 8?. Part 8 is provided with a bore or socket 8 which re-- ceivesthe shank-portion 4: of the needle by a tight, slip-joint connection.

Thehandle A is shown equipped with a ferrule, or cap, 9 which has asleeve-portion fitting over the reduced end of the handle I and whichhas an end-portion 9 having an f movable i'rom the handle, thus enablinganother needle to be substituted, at will.

What I regard as new and desire to secure by Letters Patent, is:

A device of the character described comprising a handle having one endprovided with a bore and equipped with a ferrulev embracing the end ofthe handle and having a threaded metallic socket integral with saidferrule'and received by said bore; a fitting comprising a part providedwith a bore and having a reduced threaded shank received by said socket;and a needle comprising a sheetmetal member having a tubularshank-portion fitted within said second-mentioned bore.

nel 7 through which the yarn may extend in 45 its passage from one eyeto the other. Also, as shown, the back wall of the needle is struckinwardly at points 5 and 6 to provide thread grooves adjacent the eyes.

The fitting B preferably is of a form 0 which permits it to be made on ascrew ma-
